Application filed April as, 1922. Serial no. 556,694.

To all whom it may concern:

Be it known that l, AUs'rrN F1. MILLER, a citizen of the United States,residing at Cheney, in the county of Spokane and State of Washington,have invented a new and useful Gate, of whichthe following is aspecification. i

This invention aims to provide novel means for operating a gate from aremote point. Another object of the invention is to provide novel meansfor latching the gate.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that, within the scope ofwhat is claimed, changes in the precise embodiment of the invention.shown can be made without departing from the spirit of the invention Inthe accompanying drawings Figure 1 shows in elevation, a deviceconstructed in accordance with the invention; Figure 2 is a section onthe line 22 of Figure 1; Figure 3 is an elevation disclosing one of thesupports and attendant parts; Figure is a sectional detail illustratingthe latch mechanism; Figure 5 is a sectional elevation wherein thestructure shown in Figure 4: is viewed at right angles to the showing ofthat figure; Figure 6 is a sec tional elevation showing the gate inclosed position; Figure 7 is a horizontal section taken through one ofthe supports; Figure 8 is a fragmental elevation showing a modification;and Figure 9 is a top plan of the structure delineated in Figure 8;Figure 10 is a sectional view showing a modifiedforin of the invention.

In carrying out the invention, there is provided a frame 1 including atrack 2. A guard 3 is located above the track 2 and includes endportions 5 attached by securing elements 6 to the frame 1. The numeral 1designates a gate, mounted at 7, preferably through the instrumentalityof rollers, to move along the track 2. The gate 1 is provided at one endwith a keeper 8, adapted to be received in a. seat or opening 9 formedin one end portion of the frame 1, so as to prevent the gate fromswinging outwardly with respect to the frame 1, when the isin a closedposition.

Supports 10 are located at any desired distance from the frame 1. Ashaft 11 is mounted for rocking movement in the supports 10 and in thetrack 2. Angle braclrets 12 are provided, each angle bracket includingan arm 1 1 secured to one of the supports 10, and an arm 1,.) extendedparallel to the shaft 11, the shaft 11 being journaled in the arms 1aofthe angle brackets 12. Pinions 16 are secured to the shaft 11outwardly of the supports 10 and the arms 1st of the angle brackets 12,as shown in Figure 7. Segments 17 are mounted at 18 to swing verticallyon the arms of the anglebrackets 12. Each segment 17 has a depending arm19 carrying a handle 20, the handle preferably being pivoted at 21 tothe arm, so as to hang in a depending position when not in'use, asindicated in Figure 1, the construction being such that animals cannotrub' against the handles and operate the gate. Each segment 17 includesa lateral rack 22 meshingwith one of the pinions 16 on the shaft 11.

c A' pinion or segment 23 is carried ,by the shaft 11 and is locatedadjacent to the gate 4. The shaft 11 has a limited amount of rotation.in the pinion or segment 23. The pinion or segment 23 meshes with a rack24lconstituting part of the gate 41. 1%, latch 25 is pivoted at 26 tothe hub of the pinion 23. A bow-ed spring 27 is secured at 28 adjacentto one end, to the latch 25, the other end of the spring bearing againstastop 29 on the hub of the pinion 23. The spring 27 tends to swing thefree end of the latch 25 downwardly, so thatthe latch Wlll engage with akeeper 30 projecting laterally from the gate 4. Acam or arm 31' issecured to the shaft 11 and is adapted to cooperate with thelatch 25 andwith the stop 29 in a way which will be pointed out hereinafter.

In practical operation, the segments 17 may he swung. on theirpivotalmountings 18, through the instrumentality of the arms 19 and the handles20, rotation being imparted to the shaft 11 through the racks 22 on thesegments 17 and the pinions 16 on the shaft 11.

- Passing to Figure. 1, suppose that the latch 25 on thesegment 23 isengaged with the keeper 30 on the .4. The shaft 11 rotates to a slightextent, independently of the segn'ient 23 and during this independentrotation of the shaft, the latch is disengaged from the keeper 30, andis moved to the dotted line position of Figure 4, the gate 4. thus beingset free. YV hen continued rotation is imparted to the shaft 11, the arm31 on the shaft, having disengaged the latch :25 from the zeeper 80,imparts rotation to the segment 23, by way of the latch 25, and when thesegment 23 is rotated, the segment, cooperatingwith the rack" 24: on thegate 4, slides the gate 4t from the closed position of Figure '2 to theright, into an open position. lVhen reverserotation'is imparted to theshaft 11, the gate is carried back into the closed position of Figure 2and the latch 25' engages automatically with the keeper 30, as shown inFigures 2 and 4L.

It will be understood that any suitable means may be provided forimparting rotation to the shaft'll, the structure shown in Figure lbeing retained In Figures 8 and 9, parts hereinbeforedescribed have beendesignated by" numerals previously used, witli'thesuflix a. The shaft 11is made much shorter than the shaft 11,,the supports 10 and cooperatingparts being dispensed with, the shaft 11 being journalled in a sidebearing 82 on the track 2. 'The shaft 11 carries a gear wheel or segment33, meshing with a pinion 34: on the shaft of an electric motor 35,mounted on one side of the track 2, or elsewhere. Conductors 36 of anydesired length, lead from the motor 35, switches 37 being interposed inthe conductors. I V

Obviously, by operating the switches 37, the motor may be put intooperation, the pinion cooperating with the gear' wheel or segment 33 toimpart rotation to the shaft 11, the gate being opened and closedthrough the instrumentality of the mechanism hereinbefore described.

:lleverting to Figured of the drawings, it will be understood that whenthe shaft 11 is-rotated clockwise, the arm or cam member 31, coactingwith the stop 29 imparts rotation to the pinion 23, the pinion coactingwith the rack 24 tomove the gated to the closed position shown in Figure2 of the drawings. v i

In Figure 10, the numeral denotes a support,- made of concrete, orotherwise, and provided with a slot 51. A lcver' 521s located in theslot 51 and is fulcrumed at one-end, as shown at 53 on the support 50. Aswitch 54: is disposed beneath the lever 52. roller 55, is journaledon'th lever 52.

The free end of the lever 52 is pressed upwardly by a spring5Ganterposed between the lever and the support 50. The roller 55projects slightly above the surface of the' highway indicated at 57. Avehicle traversing the highway will pass over the roller 55, depress thelever 52, close the switch and operate the date through theinstrumentality o T he mechanism shown in Figures 8 and 9.

What is vlaimed is:

1. In a device of the class described, a frame; a gate mounted to slideon the frame and. having a rack; a shaft suppm'ted rotation; a gearmember meshing with the re. the snaft having limited movement in thegear member; a latch movahly mount ed on the gear member; a keeper onthe gate wherewith the latch engages; and a means operable by theshaftfor first dis engaging the latch from the keeper and then operatingthe gear member.
